Instructions for SIDIS Experiment

1. Keep an eye on the Hall C Scaler Data GUI and make sure the rates with beam ON are steady

2. In the middle of the run, check online plots for the detectors

a. Login to cdaql1 machine and go to hallc_replay directory if you are not there already:

  > ssh cdaql1 
  > go_analysis 

b. Update the file " standard.Kinematics "

  path : 

c. At 50k events, run scripts

  for SHMS detector check: ./ <run_number>
  for HMS detector check: ./ <run_number>

Note electron tracking efficiency for HMS and hadron tracking efficiency for SHMS from resulting report files.

d. Keep charge counter running in background to keep track of charge collected:

   ./run_charge_counter.csh <detector>

The count will automatically reset when a new run starts. For LH2 and LD2, run for ~1/3 of the charge goal per run; for dummy, complete half to all of the charge goal per run.

3. After the full run, check the Good events and Update the run_list wiki

a. Make sure the standard.kinematics file was updated correctly in step 2 above.

b. Analyze the full run with :

 ./ <run_number> 

Fill in the run sheets and update the runlist:


Log LH2 as "1," LD2 as "2," and dummy as "3" in the runlist. The tracking efficiencies should not have changed much from step 2c.

c. Run this script. Make sure we see a clear coincidence time peak. Record counts to run_list wiki

 ./UTIL_SIDIS/ <run_number> <target>
  <target> = h or d
 Type .q to exit ROOT
